IMPROVEMENT IN' LIFE-PRESERVING MATTRESSES.

The Schedule referred to in the-se Letters Patent and making part of thesame.

I, J osHUA HUNT, of Providence, in the county of Providence and State ofRhode Island, have invented a Combined Mattress and Life-Preserver, ofwhich the following is a specification.

Figure 1, perspective view as a mattress.

Figure 2, perspective view as a liFe-preserver.

My invention consists in making two elongated sacks or pockets, G C,which are filled with cork, either granulated, cut into shavings, or'Vin large, flat pieces, and with the edges thereof connected with anapron, A, so that, when the two sacks are folded together upon theapron, they will just he covered smoothly thereby, and make a mattress,and when opened they will buoy up a considerable weight when vplacedupon the apron between the cork-filled sacks.

Atione end we may attach a smaller sack, which serves the purpose of aholster, B, or when detached may be used as a lifepreser\-'er.

A A A are straps or bands attached to the surface of the' sacks, bywhich to seize hold of them when in the water.

As a mattress the sacks are made of any width, so

that they will fit into the racks of steamboat-s, or vessels of anykind, and are lled with cork, which 'is the .best known lling, onaccount of its great buoyancy,

and at the same time is a good llng for a mattress, especially whengranulated or cut into shavings.

As allife-preserver, it is-unf'olded, and when in the water a person orany weight upon the apron A, within its power'of resistance, is keptafloat.

A single sack filled with cork would turn over when- Y desired.

' That I claim as my invention, and desire to secure .by Letters Patent,is-

The cork-filled sacks or pockets 'O O, united bythe apron A,whcucornbiued for a mattressl and a lifepreservcr, as above described.
